Manufacturing method of composite wear-resistant part and composite wear-resistant part
The invention discloses a manufacturing method of a composite wear-resistant part and the composite wear-resistant part. The manufacturing method comprises the following steps: preparing a ceramic inner part by adopting a ceramic product process; the method comprises the following steps: detecting a ceramic internal part fired according to a design size, carrying out simple surface treatment, and seamlessly embedding the ceramic internal part in a steel pipe; when the flange is welded and paired with the upper and lower parts or the reserved opening of the steel pipe, the flange surface is seamlessly butted with the ceramic internal part; the flange and the steel pipe are welded, a gap between the ceramic internal part and the flange face is filled and bonded through a ceramic-metal material sealing technology and common high-strength organic bonding glue, and then polishing and surface treatment are conducted; the interface is required to be smooth in surface and free of convex-concave feeling; the composite wear-resistant part is obtained; and performing a pressure test on the product, and if the hydrostatic test pressure is required to be greater than or equal to 2.0 MPa, determining that the product is qualified. The ceramic inner part is integrally fired and seamlessly inlaid in the pressure-resistant steel pipe to form the integral wear-resistant part, and the wear-resistant part is resistant to acid, alkali, pressure and wear, low in cost and long in service life and can be used for at least two years.
本发明公开了一种复合耐磨件的制造方法及复合耐磨件，包括采用陶瓷制品工艺，制得陶瓷内件；按照设计尺寸烧制的陶瓷内件经过检测后进行简单表面处理后，将陶瓷内件无缝镶套在钢管内；法兰与钢管的上下部或预留口焊接配对时，要求法兰面与陶瓷内件无缝对接；法兰与钢管进行焊接，陶瓷内件与法兰面之间的缝隙，采用陶瓷‑金属材料封接技术，利用常用高强度有机粘结胶来进行填充和粘接，再进行打磨、表面处理；接口要求表面光滑、无凸凹感；获得复合耐磨件；对产品做耐压试验，要求水压试验压力≧2.0MPa，产品即合格。本发明通过陶瓷内件整体烧制，无缝镶嵌在耐压钢管内，加工成整体的耐磨件，耐酸碱耐压，抗磨，成本低，使用寿命延长，至少两年使用。
